MORNING gays,today I will share you eye problems commonly occurring in teenagers,at middle age and in later life.
During the teenage years,the body is rapidly changing. Unique vision issues can develop between the age of 13 and 18,which are commonly linked to development during puberty.

Another one is Glaucoma,which causes by the increased intraocular pressure.
